. Appiieation mea october 9, i926.r serial Nori-10,632.

' This invention relates to ine-ans for se- The objects of the linvention are to provide simple,V efficient, vinexpensive and reliable means for releasably locking and hold'- ing a dumping body in aiixed 'loadingv y'position without the use of springs or auxiliary fastening'means. j l

The inver'ition will Ylirst be hereinafter more particularlydescribed with reference to the accompanying drawings, which are to be taken as a part of this specification, and

then pointed out in ofthe description.

'In said drawings, Fig. l is a side elevation of'a common'form of truck or motorv vvehicle provided with a dumping body having my improved releasable locking and holding means applied thereto;

Fig. '2 is asi le elevation "of the releasable dumping body securing means showing' the" same` in full "lines in normal locking position A and in` dottedlines in released` positioni` parts of thelongitudinal bars of the lvehicle frame being,Y shown in section; 7

Fig.` 3 yis a detail sectional view taken onk Fig.v t is` a detail sectional view takenon the line 4&4 of Fig.` 2.

Referring to said drawings, inwhich theA same reference characters are used to denote corresponding lparts in different views, the Vletters A7 A,v denote the side bars: o the frame or chassis of an ordinary motor vehi-` instance is shown hinged near its lrear fend to said traine Iso that itsvfront end may be raised to throwsaid body into an inclined` position for dumping oremptying itscontents. Said side bars A are preferablyconstructed of channel iron lor steel arranged fsoj that the: flanges on oneextend inwardly `toward the flanges on the other, but other constructions maybe u sed, as `my improved` dumping body securing means may be Aused( in connection witlrvarius kinds of duin-p.- ing bodies,..whether supported ong'a chassis or other v,vehicle -fra-ine having` side bars-f wliichsa'id securing meansmay engage..

The illustrated securing'means comprisgis the claims at the end` I n operator standing beside the machine and a pair of bars C andv D connected in substantially parallel relation by meansfof a pair of substantially vertical levers E pivotedv at a point intermediate their length to the transverse bar C and having their upper ends pivoted 'to the ytransverse bar D; the

lowerpends thereof being formed or providedfwith toe-pieces @which extend later- -fin ally in the same direction andare adapted to ltake under the side bars A of the chassis 'or'in'achine frame, as shown more clearly in Fig-.Bof the drawings. Fdenotes a'leve'r pulled or shoved'in the direction of its length,v for the purpose, of engaging or ldis-` vengaging'the toe-pieces of the levers E, E, with the side bars A.V A connecting rod or link H, having one end pivoted `to the transverse banDextends 'inwardly and downwardly 'therefrom and its `lower end is' pivotedto the lower .curved end ci the togglelever F; said .link extending in alinenient-"with itspivotal'connection withl said toggle lever and with the pivotal connection between said fixed bar and said toggle lever when the upright armof the latterl is in a substantially vertical position7 so that when the vogglefleverv is thrown into position to lock the dumping body in loading position said pivotal. connections will be thi-own out. ,of y,alinement, whereby vmovement of lsmid, handlever will thiowthe toe-pieces of said laterally swinging leversy simultaneously in the same direction and cause them to' engage the chassisnrvehiClerame, thereby locking the swinging levers and through them locking the Adumping bodyto the vehicle frame.

I thus provide a simple and inexpensive dumping body securing and releasing de. vice which -isvpfositive in its action vand* not liableto get out of order, and which consists ,of yfew l'parts adapted to be easily assembled or taken apart for renewing or khaving its lower curved end pivoted to the repairing anyj.worn or vbroken part7 and f which'in practical'use will serveto positively lock the hinged body to the chassis or vehicle frame on which lit ismounted and hold'the two partstogether without danger.

of beingxreleased accidentally orotherwise thanby vmovement ofthe operating lever so as to throw the pivotal connection between the toggle lever and link connectingitwith the movable bar out of alineinent with the fulcruin ot the toggle lever.

It will be understood of; noursethat the torni ot the hand lever and toggle lever and twisted swinging levers may be changed and that various changesniay be madezin details without departing from the spirit and scope my invention. y .y y

lt will be observed that the lined and movable bars C and D, as shownl inthe drawinggs,v are not bars, as they may be, but composite structures, each consisting ojl two vflat metal bars placed side `by side and secured together by fastening bolts. For increased strength and durability, a

,stout metal bar c and a thin lmetal bar o1 are used to -l'orm the supporting bar C; these two barsbeing spaced` apart sui'hciently to receive therebetween the lower end ofl thc toggle lever F, and a biturcated end portion ot the connecting rod or link l-'l which straddles the lower` end portion of the toggle lever tor pivotal connection therewith, yas shown in Figs. 2 and 3, and said bars@ and o1 have registering holes therein to receive boltsyl, (lfig. Q) ,whichflorm the pivotal connections between the supporting bar and the levers E. rl`he vertically disposed swinging ylevers E are each termed by twisting a piece olf dat metal at a point intermediate its length. so as to provide an upper portion or shanlr arranged substantially atV right angles'V to the lowerend portion thereof, the extreme lower endbeingbcnt laterally tov torni `the toe-piece e arranged to taire under the 'lower flange ot' the adjacent sidebar Ao't' the vehicle trame; saidupper end portion or shank being arranged tlatwis'e, between the flat metalv bars o and c1. inner 'dat metal bar c liasat one endthereoiI a depen/d-v ing lug` or projection c2 which abuts against one of the side` bars A ot the vehicle trame' at the side thereot` opposite the adjacent vertical lever T., so as to prevent. sidewise movement ol" the dumpingbody when the operating lever is pulled toward the oppo-y site. .fide of the machine `into position to loch the dumpingbody down upon the vehicle trame. rlhe bar D is also shown foriii'ed ot two llat i etal bars secured together side by side and spaced apart to receive therebe-v tween the pivoted end ol the linlrH, and also receive and guide the upper end oit the toggle lever F. The supporting lbar `C may be conveniently secured to the lower front end board Z). ot' the dumping body B, as shown, by means ot 'fastening bolts K 'nserted through registering` holes in the two flat metal bars which form the composite C and through holes in the front lend board ot the dumping body. One ot these bolts is shown in theY detail viene-Fig. fl.
